[TheForge] Re: repost of propane cylinder cutting

[Mike Sweany]

If you go shooting pure oxygen from  torch head into a cylinder with any kinda fuel you get combustion.
In our Haz/mat class they showed what was left of the highway after a liquid Oxy truck was leaking ontop the road. Nobody thought it was big deal cuase there was no fuel present.  
The asphalt soaked up the pure oxy and when some Nicotine addicted fireman walked up with a lit cigrarette everbody, including a fair bit od road and the truck disappeared.
It's not IF when cutting cylinders it's WHEN

Couldn't the flame be due to the cutting torch? Wouldn't take much 
unburned fuel to have a flame like that.
